YOUR eyesight could be as good as an astronaut’s if you can spot the space walker’s legs on the International Space Station.
NASA astronaut Mark Vande Hei posted a picture from a Russian spacewalk and issued a challenge to viewers.
Hidden in the picture is an astronaut’s legs dangling off the side of the space station.
In the picture, taken February 2 2018, a breath-taking view of Earth can be seen amid the vast landscape of space.
Cosmonauts Alexander Misurkin and Anton Shkaplerov set a new record for the longest Russian spacewalk that day.
The pair spent eight hours outside the ISS to install new parts to an antenna to improve communications with Russia’s flight controllers on Earth, CNET reported.
If you’re in need of a cheeky hint, check the top-centre of the picture.
It might help if you zoom in to take a closer look.
Once you’ve found the legs, take a moment to appreciate the vast size of the ISS compared to the astronauts lower limbs.

On the original post’s thread, people shared their delight in finally spotting the legs.
One person wrote: “It took me forever but I found him!!”
Another commented: “Really had to zoom in on my smartphone to see his legs. Gives the dual perspective of just how big AND small the ISS is.”
Others talked grand view of space and discussed ideas about the world we live in.
Someone said: “Nothing except BILLIONS of other worlds waiting for us!”
Another said: “Its just amazing when we think that we’re here in our planet and someone like us is there ! Ooohh !”
